Application of linear induction motors (LIM) on enterprises of non-ferrous metallurgy involves accomplishing specific engineering and economic tasks of building a power unit of electric drive, engineering, modeling, designing, as well as technical and economic assessing of electric drive indicators. The paper presents an overview and analytical information on these issues, which allows industry specialists to perform a feasibility study of LIM usage. The prospects of LIM application in electric drives of processing and auxiliary equipment of non-ferrous metallurgy sub-sectors are justified and respective examples are given. The designing tasks of layout synthesis and calculation of the output characteristics with corresponding modeling aids are classified. It is established that there are no methods and means of solving both problems currently prevalent and accepted by professional community. Low operating rate of an electric drive and edge effects reduce energy data of LIM. At the same time, electric drives based on LIM or rotary motion electric motors are competitive variants of a linear electric drive. A mathematical model for layout synthesis of LIM is suggested. The model includes the means of forecasting estimation of electromagnetic, technical, weight-size and dynamic parameters of the object. On this basis, the main magnetic field of LIM was calculated. The LIM service life model calculation is implemented, what has allowed to evaluate cost-effectiveness of LIM application. It is established that in certain situations the use of a linear electric drive with LIM is advisable and cost-effective. The question of expediency of LIM usage in each concrete case should be settled based on a feasibility study.

The work deals with the problem of energy efficiency of autonomous indication and lighting systems for unregulated ground pedestrian crossings equipped with a solar panel being significantly important in conditions of insufficient insolation and low temperatures. The scientific objectives of the work are considered to be as follows: analysis of the conditions affecting the uninterrupted functioning of autonomous indication and lighting systems of unregulated ground pedestrian crossings equipped with a solar panel; selection and justification of objective factors, considering which allow the implementation of battery charge saving modes by optimizing the functioning algorithm of autonomous indication and lighting systems for unregulated ground pedestrian crossings equipped with a solar panel. The work presents the directions for possible technical implementation of increasing the energy efficiency of autonomous indication and lighting systems for ground pedestrian crossings equipped with a solar panel, based on obtaining optical information about vehicles moving in the direction of the pedestrian crossing and stabilizing the brightness contrast of the traffic light signal and the background where it is observed by vehicle drivers.

The foundry industry is regarded as one of the most energy-intensive industrial sector due to its energy consumption up to 9 MWh/ton of produced metal. As a result, many companies are trying to increase the energy efficiency of their foundry plants. Since many energy-saving technologies are proposed by manufacturers and the literature, choosing the most appropriate one is a difficult task. Moreover, being updated with the available energy-saving solutions is complicated because of the quick technology advances. Consequently, this paper aims at investigating the recent and future opportunities and investments for reducing the energy consumptions of the technologies of Italian foundry companies. Additionally, it aims at presenting a list of available technological solutions validated by Italian experts. To this end, the Energy Audits developed by 231 plants were analyzed to extract the implemented and planned interventions. Furthermore, the economic data available within the Energy Audits were studied to determine the advantages of a given technological solutions compared to the others. It emerged that the companies are strongly investing in increasing the efficiency of the auxiliary systems such as compressors and motors. The outcomes of this study can assist both researchers and energy managers in choosing the most appropriate energy-saving solutions.
